Read the whole thing, including the absurd attempt to blame the descent of the left on conservatives:

But after years of being the targets of inflammatory rhetoric, not only from fringe groups but also from such mainstream conservative politicians as Newt Gingrich, the left has gone on the attack.

The left has become disfigured because the excess that dominates the lefty blogs is absorbed by rank-and-file activists and encouraged by the Democratic Party leadership, which embraces, posts at and praises the blogs that are among the angriest and most vulgar/profane/hate-filled.

The collapse of the left’s ability to engage in politics will continue and in fact accelerate unless and until the leaders of the Democratic Party rebuke the party’s activist base and its spokesmen, which is unlikely to happen anytime soon.

The best thing the GOP has going for it in November, 2006 and in the presidential campaign to follow is the fury of the unhinged left. The vast majority of Americans reject politics of this sort, but there’s no hiding what the left has become or the Democrats’ endorsement of it.
